This is a very interesting video series done by HPF documenting the details behind their motor builds for their big hp setups. When I say big HP, I mean big horsepower, as in up to 1,000 at the wheels. These videos are in very high quality and it is recommended any and all BMW enthusiasts take a look, this is how it is done.

lol!! That was my whole point.. the videos were works of art no doubt about it. I've been building engines for 20 years. I remember before the days of CNC equipment... I've used a electric drill to hone my cylinders lol!!! The engine builder was a quality mechanic nobody is arguing that. However, I just didn't see anything I wouldn't expect from any machine shop.. I can find half a dozen in Houston alone that are just a good.

Now if I had seen some serious custom machine work taking place, I would have had a different view. They decked the engine, surfaced the head, used a CNC to bore the cylinders with a TQ plate.. all standard procedure. The equipment used was pretty common in reputable shops these days. Again, there are BMW machine shops that do custom crank grinding, use custom sized rods and non-BMW coated bearings. Installing a sleeve to me isn't anything custom.. I've done it on a few boosted Hondas.. big deal.

Again.. GREAT ENGINE BUILD! It just doesn't warrant a pedestal or altar.. According to HPF site.. the builds cost $3K.. To me that is an EXCEPTIONAL price for what was done. Most BMW builders charge three times that. That alone makes it a great build to me and a shop I would consider using.. just based on price alone.

Noone is ever happy. Hpf shares more info about there product then every other company.

I agree.. I'm seriously considering making the switch. I've weighed my costs to go with a built motor, T-Trim at 18 PSI with a custom tune and in the end I still won't have what a HPF Stage 2.5 kit is proven to put down. I sent HPF sales an email..

I'm having hpf2.5 build now. That motor in the vids might be mine. I noticed there blown headgasket comment. My car had blown headgasket. Lol. Just call hpf and ask for David. You can almost always get ahold of him.

I think you will be happy with that decision. I have beat on mine for about a year now and haven't had one issue..knock on wood. Driven it in snow storms, rain storms and 100+ degree weather and never a hiccup. Plus, it gets down the road pretty quickly!
